Hey @psankhe28 - I've reviewed your changes - here's some feedback:

Overall Comments:

• The implementation doesn't match the API specification - the spec describes using the TUS protocol for uploads but the code implements basic multipart upload instead. Please implement proper TUS protocol support or update the API spec accordingly.
• Security concern: Writing temporary files to /tmp without size limits is dangerous. Consider using stream processing or implementing proper size limits and cleanup on error paths.
• Several checklist items are incomplete: missing tests, documentation, and type annotations. Please add these before the PR can be merged.

Here's what I looked at during the review

• 🟡 General issues: 2 issues found
• 🟡 Security: 1 issue found
• 🟢 Testing: all looks good
• 🟡 Complexity: 1 issue found
• 🟢 Documentation: all looks good

issue (bug_risk): Add proper cleanup in error cases and improve error handling

Temporary files aren't cleaned up if an error occurs. Consider using a try/finally block and return a sanitized error response instead of exposing raw S3Error messages.
